Description:

The NTE7086 is a sync•deflection circuit IC in a 20–Lead DIP type package dedicated to CRT display use. This device can be connected to the NTE1773/NTE1797 (for vertical output use) to form a sync•deflection circuit that meets every requirement for CRT display use.

So far, IC’s for color TV use have been applied to the sync•deflection circuit for CRT display use and general–purpose IC’s such as one–shot multivibrators, inverters, and a lot of transistors have been used to form the peripherals such as the sync input interface and horizontal phase shifter.

The NTE7086 contains these peripherals on chip and adopts a stable circuit for horizontal oscillation from 15kHz to 100kHz aiming at improving the characteristics required for CRT display use.

Features:

• The Horizontal Oscillation Frequency can be Adjusted Stably from 15kHz to 100kHz.

• The Horizontal Display can be Shifted Right/Left.

• The Horizontal/Vertical Sync Input can be used intact Regardless of the Difference in Pulse Polarity and Pulse Width.

• The AFC Feedback Sawtooth Wave can be Obtained by Simply Applying a Flyback Pulse to the IC as a Trigger Pulse.

• Any Duty of the Horizontal Pulse Can be Set.

• Good Linearity because DC Bias at Vertical Output Stage is Subjected to Sampling Control within Retrace Time.
